Title (EN) DEVICE FOR EFFECTING A CONTACT BETWEEN THE CONDUCTIVE PATHS OF PRINTED CIRCUIT BOARDS AND CONNECTION PINS
(FR) DISPOSITIF POUR REALISER UN CONTACT ENTRE LES PARCOURS CONDUCTEURS DE PLAQUES A CIRCUITS IMPRIMES ET DES BROCHES DE CONNEXION
Abstract: front page image
(EN)The device comprises a support (1) to which is fixed an induction loop (3) through which a high frequency alternating current passes. By displacing the support (1) or the printed circuit board (4) provided with contact pins (2) to be welded, a plurality of contact pins (2) is brought into the influence zone of the alternating magnetic field at the same time as the welding material (5) and the metallised passage holes (6) intended to be brought in contact with the pins. Owing to an appropriate arrangement of the induction loop (3), a well defined and uniform heating of the pins (2) and the contact zones is achieved. The device allows simultaneously a faultless welding of several contact pins (2) arranged into one or several rows and being part of connection strips fixed to printed circuit boards.
(FR)Le dispositif comprend un support (1) auquel est fixee une boucle d"induction (3) parcourue par un courant alternatif a haute frequence. Par deplacement du support (1) ou de la plaque a circuits imprimes (4) munie des broches de contact (2) a souder, une pluralite de broches de contact (2) est amenee dans la zone d"influence du champ magnetique alternatif en meme temps que le materiau de soudure (5) et les trous de passage metallises (6) destines a etre mis en contact avec les broches. Grace a un agencement a de la boucle d"induction (3), on obtient un chauffage uniforme bien determine des broches (2) et des zones de contact. Le dispositif permet ainsi de realiser simultanement un soudage sans defaut de plusieurs broches de contact (2) disposees en une ou plusieurs rangees et faisant partie de bandes de connexion fixees sur des plaques a circuits imprimes.
